Description
Technical field
The utility model relates to a kind of smart impact machine AC servo fluid power system.
Background technology
Smart punching is a kind of advanced person's processing technology, smart impact machine is widely used in the processing of engineering goods and part at present, but conventional hydraulic adopts the mode of valve control at present, when system high pressure, high speed operation, motor is in the state of operating at full capacity, when system high pressure, tick-over, motor still is in the state of operating at full capacity.Part liquid flows into oil cylinder, and another part liquid flows into fuel tank by control valves such as overflow valves, causes energy waste, causes simultaneously Hydraulic System Fever.Smart punching need to be converted to work speed 5 ~ 40mm/s from fast forward speed 200mm/s, and conventional hydraulic has impact by the flow speed control valve conversion, produces vibration, affects precision.Therefore need a kind of novel hydraulic system, improve the effective running efficiency of lathe and energy-saving and emission-reduction function.
Summary of the invention
Technical problem to be solved in the utility model is large for present smart impact machine Hydraulic System Fever and large deficiency is impacted in conversion, and a kind of Novel precise impact machine AC servo fluid power system is provided.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to be:
Smart impact machine AC servo fluid power system, comprise the smart impact machine oil cylinder that fills hydraulic oil, the valve control system that links to each other with smart impact machine oil cylinder, also comprise the pump control system that is connected on the described smart impact machine oil cylinder, described pump control system comprises servo controller, servomotor, oil pump, the output of described servo controller is connected with servomotor, described servomotor is connected with described oil pump, described oil pump is provided with the return valve of regulating its pressure, also be provided with the sensor for detection of its pressure feedback value on the described oil pump, the output of described sensor accesses the input of described servo controller.
In such scheme, described servomotor is AC servo motor, is connected with described servo controller by the encoder cable.
The principle of the utility model drive system is, advance a little to be in the phenomenon of high pressure, tick-over state during according to smart impact machine work once the mistake worker, adopt novel AC servo fluid power system, cross the worker when smart impact machine one and advance a little, drive system transfers the pump control to by the valve control, return valve serves as safety valve fully to be used, and the hydraulic oil that oil pump extrudes all enters smart impact machine oil cylinder, not overflow, advance a little so that crossed the worker, servomotor is in low pressure, lower-speed state, thereby energy savings reduces system's heating; Closed-loop control is carried out in the pressure set points contrast computing that the pressure feedback value that servo controller detects by sensor and computer are given, thus start and stop and the rotating speed of control servomotor, and the curvilinear motion that servomotor speed changes is very steady.
The beneficial effects of the utility model are: changed the deficiency that the conventional hydraulic heating is large and the rate conversion impact is large, realized the closed-loop control of hydraulic system pressure, controlled in real time detected pressures, pressure controling precision is high, improved production efficiency, reduced and produce noise; Compare with traditional valve control system, can reduce by 70% energy consumption, structure is advanced, safe and reliable, energy-conserving and environment-protective.
